Many modern political dynasties are built on "like father, like son." However, Mitt Romney's cautious presidential bid in many ways highlights how he's different from his old man. In 1967, former Michigan Governor George Romney candidly revealed that he had changed his stance on the Vietnam War with the remark, "When I came back from Vietnam, I had just about the greatest brainwashing that anybody can get." Most pundits agree that this remark effectively ended George Romney's 1968 presidential campaign.
